Good day

I tried adapting the template example to try and add two strings, one left and one right of a logo

<DataTemplate x:Key="PagePresenterHeaderTemplate">
            <Grid Margin="5">
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto" />
                    <RowDefinition Height="12"/>
                </Grid.RowDefinitions>
                <Image Source="/Pathname"
                       Height="50" Width="50"
                       HorizontalAlignment="Center"/>
                <Label
                      Height="50"
                      Content="{Binding Path=left}"
                      Padding="10,0"
                      VerticalContentAlignment="Center"/>
                <Label
                      Height="50"
                      Content="{Binding Path=right}"
                      Padding="10,0"
                      VerticalContentAlignment="Center"
                    HorizontalAlignment="Right"
                    HorizontalContentAlignment="Right"/>

                <Border
                      BorderThickness="1"
                      BorderBrush="Black"
                      Height="2"
                      Margin="20,0,20,0"
                      VerticalAlignment="Bottom"
                      Grid.ColumnSpan="2"
                      Grid.Row="1"/>
            </Grid>
        </DataTemplate>

and then created a class

public class Headerstrings
    {
        public string left;
        public string right;
    }

and tried to bind using

// apply header template
            reportObj.PageHeaderTemplate = this.Resources["PagePresenterHeaderTemplate"] as DataTemplate;

            Headerstrings headerstrings = new Headerstrings();
            headerstrings.left = "left";
            headerstrings.right = "right";

            reportObj.PageHeader = headerstrings;

What am I doing wrong?  Is that not how it should work?
